Patented Dec. 29, 1936 UNITED STATES PATENT OFFICE ROCKER STUD BEARING 1 Claim.

The invention relates primarily to the provision of an improved construction of rocker stud bearing for the lay sword of looms, and has for its object the provision of a bearing member that may be readily applied to and removed from a loom frame, and that is provided with means for adequately bracing the bearing so as to prevent undesirable movement of the lay sword while in operation, and that is also furthermore designed to reduce the shafting required for carrying the lay sword.

The invention will be described in detail hereinafter and will be found illustrated in the accompanying drawing, in which Figure 1 is a top plan view of the improved rocker stud bearing showing the parts supported in the bearing in broken lines,

Figure 2 is a side View in elevation of the parts shown in Figure 1,

Figure 3 is a front end view, and

Figure 4 a transverse sectional View on the plane indicated by the line 4-4 of Figure 1.

Referring to the drawing in which similar reference characters are used to designate correspending parts throughout the several views, the improved rocker stud bearing comprises a body generally designated I0 and including a plate II provided with openings I2 for the reception of bolts or the like for securing the body member I0 to the frame member of a loom.

Projecting laterally of one side of the plate I0 is a tubular nipple I3, the bore I4 thereof being in alinement with an opening I5 in the plate II, said bore I4 and opening I5 providing a bearing member for a shaft I6.

Extending from the opposite side of the plate I I from the nipple I3 is an arm I1 having its extremity turned at a right angle thereto as shown at I8 and in substantial parallelism with the plate I I, the extremity of said arm being also enlarged as shown at I9 and provided with a bearing opening 20 alined with the opening I5 and the bore I4 of the nipple I3, and supporting the opposite end of the shaft I6, hereinbefore referred to.

Extending laterally from the arm I'I is a leg member 2|, said leg member having the portion adjacent to the arm I1 inclined upwardly and outwardly from the arm I1 as shown at 22, and

its extremity extended substantially horizontally as shown at 23 and provided with an opening 24 to receive a bolt or other driven member to secure the extremity of the leg member to a skirt-board or the like on the loom frame.

Included in the drawing are also shown bushings 25 and 26, and obviously the employment of bushings would be an advantage, but I do not limit myself to the use of the bushings but may mount the shaft I6 directly in the bearing open- 10 ings I4, I5, and 20.

The shaft I6 is adapted to have secured thereto a lay sword member 21, provided with an enlarged tubular end connection 28 to receive the shaft I6, and 29 designates a set screw for se- 15 curing the lay sword and the tubular member for rotation with the shaft I6.

The usual lubricating openings are provided for the shaft I6, as designated 30 and 3|, and preferably have pressure lubricating members of 20 which there are a number of types on the market secured therein.

While I have shown and described the invention for use in connection with mounting a lay sword of a loom, the bearing may obviously be 25 used for other purposes where a rocker shaft is called for, and I do not, therefore, limit myself to the specic application as herein described.

What is claimed isz- A rocker stud bearing for loom swords, com- 30 prising a plate adapted for attachment to a loom frame, a central bearing nipple extending integrally from one side of said plate, an arm extending integrally and laterally from the opposite side of said plate in offset relation to the 35 nipple, the free end of said arm extended at an angle thereto and in substantial parallelism with the plate, said free end enlarged and having a bearing opening therein, a shaft journaled in said bearing opening and nipple, and a leg mem- 40 ber extending integrally from said arm between said plate and free end upwardly and forwardly in the opposite direction to the free end of the arm and having a substantially horizontal portion adapted to be secured to a skirt-board of the 45 loom frame.
